▎ 摘　　要

NOVELTY - High-strength and high-performance concrete pavement brick admixture, comprises 10-20% silica fume, 30-50% micro-bead, 15-30% heavy calcium powder, 2-8% talc powder, 1-2% water reducing agent, 1-3% rubber powder, 0.1-0.2% starch ether and 5-10% sound-absorbing and shock-absorbing materials. The admixture can replace part of the cement with a content of 10-40% of the original cement to produce concrete pavement bricks with a strength level above C60. USE - High-strength and high-performance concrete pavement brick admixture. ADVANTAGE - The high-strength and high-performance concrete pavement brick admixture is capable of improving compression strength brick and abrasion resistance, and reduces the road brick road surface driving noise. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of high-strength and high-performance concrete pavement brick admixture
